Biotechnology Topics in Depth
DNA Technology
All of the genetic information or DNA in a cell is its genome. Huge doesn't even begin to describe the size of the human genome. It's so big that it can be overwhelming, even to computers. We are u...
Gene Expression
We have to use DNA technology to clone the gene we want to study. It's a necessary evil. After the gene is cloned, we can get to the good stuff and look at different gene sequences and expression....
Gene Function
Sure, DNA technology and gene expression are important, but we all know the proteins deserve all of the credit. They are the ones actually doing the work. To see what a gene actually does, scientis...
Organism Cloning
When most people think of cloning, they usually think of Dolly the sheep, who in 1996 became the first mammal to be cloned from an adult cell2. Unfortunately, Dolly didn't live to a ripe old age, b...
Forensic Applications
You really should finish studying for your biology exam, but you just can't tear yourself away from the latest episode of CSI. After all, you'll learn a little about biology just by watching, right...
Medical Applications
Some of the most immediate benefits of biotechnology can be seen in the medical field. Advances in biotechnology can be extended to the detection of pathogens or medical diagnoses, gene therapy, an...
GM Foods
Unless you've been living under a rock, you've probably heard about genetically modified, or GM, foods. GM foods are foods that have had their genes messed with in one way or another to benefits us...
Common Mistakes
DNA Technology
DNA will migrate to the positive electrode due to its negatively charged backbone. This is usually the red colored electrode, so remember, "run to red." Electro this, electro that, e...
